What does it mean when you dream someone is chucking you in you dream?

It means you have repressed sexual urges towards whoever that person was.

The interpretation depends on whether the question involves an odd referral to sexual activity or whether it actually means "chucking" which is part of the process of chopping firewood. Since it is almost certainly the former, the dreamer should know that sexual dreams are caused by one's own, natural bodily hormones. Such dreams do not provide any information of any kind about the other person's thoughts or feelings.
